02-03 and 03-04 were awesome seasons for Belfour with the Leafs, he was runner up for the Vez.
On July 2, 2002, Belfour signed as a free agent with the Toronto Maple Leafs after then Leafs goaltender, Curtis Joseph, chose to sign with the Detroit Red Wings. Belfour rebounded after a dismal season with the Stars, winning a franchise-record 37 games and helping his new team finish second in the Northeast Division. His 2.26 GAA ranked 11th in the league. During the season, he was invited to play in the mid-season All-Star Game in Florida, but a back injury forced him to miss the event. On April 1, he earned his 400th career win in a match against the Devils. In the playoffs, Belfour posted a 2.71 GAA and a .915 Save% in seven games in an opening-round loss to the Flyers. On April 16 in Game Four at the Air Canada Centre, Ed made 72 saves before losing 3-2 on an overtime goal by Mark Recchi. Belfour finished as runner-up for the Vezina Trophy, won that year by the Devils' Martin Brodeur.
In 2003–04, he posted a 34-19-6 record in 59 games as the Maple Leafs finished fourth overall in the conference standings. He recorded a 2.13 GAA and a .918 save percentage along with ten shutouts. On April 3 in the final game of the season, Belfour posted a 6-0 shutout over the Senators to secure home ice advantage in the opening round of the playoffs. That shutout gave him 10 on the season, setting a new personal best. In the playoffs, Belfour posted three shutouts in the opening round against the Senators, setting a record for shutout streaks in a series. However in the second round, former teammate Jeremy Roenick eliminated the Leafs by putting a game 6 overtime goal past Belfour.
Good enough to be remembered in my opinion.
